Laser Ignition System for an Internal Combustion Engine (continued) pdf&AD= ADA; backcocodembe.cf Laser ignition can enhance the combustion process and minimize Compared to a conventional spark plug, a laser ignition system should be a favorable.
Among these, pre-ignition and backfire remain the biggest challenges for commercialization of hydrogen engine. Sustainability with regard to internal combustion engines is strongly linked to the fuels burnt and the overall efficiency.
LASER IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE
Laser ignition can enhance the combustion process and minimize pollutant formation. This paper is on laser ignition of sustainable fuels for future internal combustion engines. Ignition is the process of starting radical reactions until a self-sustaining flame has developed.
In technical appliances such as internal combustion engines, reliable ignition is necessary for adequate system performance. Ignition strongly affects the formation of pollutants and the extent of fuel conversion . Literature Survey: The conventional engine has been modified with a view to conduct feasibility Experiments using laser ignition .
The engine has been modified replacing the conventional spark plug by a window installed into a cylindrical mount. In technical appliances such as internal combustion engines, reliable ignition is necessary for adequate system performance.

Literature Survey: The conventional engine has been modified with a view to conduct feasibility Experiments using laser ignition . The engine has been modified replacing the conventional spark plug by a window installed into a cylindrical mount.
The position of the focusing lens inside the mount can be charged to allow variations of the location of the initial optical breakdown. It has been observed that Compared to conventional spark plug ignition, laser ignition reduces the fuel consumption by several per cents.
Another important question with a laser ignition system is its reliability. It is clear that the operation of an engine causes very strong pollution within the combustion chamber.
Laser Ignition System
Deposits caused by the combustion process can contaminate the beam entrance window and the laser ignition system will probably fail. Unfortunately, conventional spark plug ignition shows a major disadvantage with modern spray-guided combustion processes since the ignition location cannot be chosen optimally. It is important that the spark plug electrodes are not hit by the injected fuel because otherwise severe damage will occur.
Additionally, the spark plug electrodes can influence the gas flow inside the combustion chamber. ThisPlasma is heated by the incoming laser beam and a strong shock wave occurs.
The expanding hot plasma can be used for the ignition of fuel-gas mixtures. Lasers provide intense and unidirectional beam of light. Laser light is monochromatic onespecific wavelength. Wavelength of light is determined by amount of energy releasedwhen electron drops to lower orbit.
LASER IGNITION SYSTEM FOR INTERNAL COMBUSTION ENGINE
Light is coherent; all the photons have same wavefronts that launch to unison. Laser light has tight beam and is strong and concentrated. Main parts of laser are power supply, lasing medium and a pair of precisely aligned mirrors.
The most important part of laser apparatus is laser crystal. Most commonly used laser crystalis manmade ruby consisting of aluminum oxide and 0. Crystal rods are round and end surfaces are made reflective.Photochemical ignition.
Voltage can even be stepped up before sending it to the coil, so the coil can create a much hotter spark, on the order of 50, volts instead of 20, volts that is common with the mechanical systems.
Systems like these have some substantial advantages.
Jitendra Kumar kumar. In LIS it doesn't require to maintenance to remove may be classified into one of the following four carbon deposit because of its complete combustion schemes: The life and durability are far better than the plug it cannot change it place it need to place normal spark plugs.
